Specification of Letters Patent.

Patented Jan. 3, 1911.

To all 'whom it may concern:

Be it known that we, CHRISTIAN HIERING and ALBERT FULLER, citizens ofthe United States, residing in the city of Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Bag-Fasteners; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make,construct, and use the same, reference being had to the accompanyingdrawings, and to letters Of reference marked thereon, which form a partof this specification.

rlhe object of our invention is to simplify the structure of a bagfastener, so as to render the saine positive yet effective in operation,simple in construction, and durable in use.

ln carrying out our invention, we make use of the various structuresillustrated in the accompanying drawings, in which- Figure 1 illustratesa side elevation of a bag frame having an improved bag fastener ateither end of the frame. Fig. 2 is a plan view of the same. Figs. 3 and4 are side elevations of the improved bag fastener, a modified formthereof being shown in Fig. 4. Figs. 5 and 6 are bottom plan views ofthe same. Figs. 7 and 8 are vertical sectional views of said fasteners,taken on lines m-oo of Figs. 3 and 4 respectively. Figs. 9 and l0 arefront elevations of the slidable operating and locking members. Figs. lland l2 are plan views of the chambered base; and Fig. 18 is a frontelevation of the slidable locking member in which a slit is substitutedfor the slot illustrated in Figs. 9 and l0.

Similar letters of reference refer to like parts throughout thespecification and drawings.

In bags of the type illustrated, it is customary to provide adjacent toeach end of one of the bag frame members o, a chambered base o, securedto the bag frame by means of a pair of integral tongues c, insertedthrough apertures in the bag frame member a, and clenched over in anysuitable and convenient manner. The chambered base o as illustrated,(Fig. 3) is provided upon one side with a rectangular notch ol, for thereception of the hook or clip c, said hook or clip being secured to theopposite hinge member f. The forward end of the hook or clip c isprovided with a rectangular notch g. The base b and hook e are maderights and lefts and so located upon the respective bag frame members aand f respectively, that the hook member will register with the notch d,with the notch g entirely within the chambered base.

The top of the chambered base Z2 is provided with slots 71 for thereception of the tongues z', which are formed integrally with theslidable operating member y',said tongues passing through the slots itin the base and the reduced portions a are turned over on the flatspring c, thus combinino` the slidable operating member j with the baseo, by the interposition of the flat spring 7o, so that the same hassliding engagement with the base o and spring 7c, through the slots tand the tongues z'.

ln the modified form illustrated in Fig. 4, the base b is not providedwith a rectangular notch d such as shown in Fig. 3, but the slidablelocking and operating member y' is provided with a depending tongue Z,which is secured in any convenient manner rto the upper inside of themember j, said tongue passing through the center slot 7L 0f the base o,and through a similar slot z" formed in the flat spring 7c. We have alsodiscovered that the slot m can be dispensed with, and a slit m such asis illustrated in Fig. 13 substituted therefor, in which case, the slotsit in the base o are somewhat lengthened and the metal of the tongues z'below the slit m is bent in the same manner as above described.

The spring lo may be of any convenient form, and is secured and held inposition in the chambered base b by the inturned and reduced portions no-f the tongues z, to be hereinafter described, and is preferably of thesame shape as the inside of the base, with sufficient clearance on thelongitudinal sides to permit those parts of the tongues which are notinturned to freely slide in the slots h formed in the base o.

When the bag frame sections a and j are separated or opened, theslidable operating member j is retained in its unlocked position bymeans of the spring 7c which bears upon the reduced inturned portions ofthe tongues z', and when said bag frame sections are again moved towardeach other to cause the vsame to assume their closed relation one withthe other, the operating member y' is by hand forced back into lockedrelation with the hook or clip e. In order to open the bag, the member jmust be forced by hand out of locked position with the hook or clip e.

We have found it highly advantageous to construct the locking member inthe manner illustrated in Figs. 9 and 10 of the drawings, in which thetongues i are formed with an inwardly projecting slot m, the width ofwhich approximately corresponds to the thickness of the metal in thebase a, plus the thickness of the metal of the spring Ze, and providingone side of said tongues with a reduced portion as at n, so that afterthe tongues have been passed through the slots lz in the base Z), thereduced portions u of the tongues vl by means of suitable dies, are bentaway from the slot, and toward each other over the spring 7c, as clearlyindicated in Figs. 5 and 6 of the drawings. In practice, we havediscovered that by making the slot fm, in the tongue d of a widthapproximately the thickness of the metal in the top of the base Z), thespring 7c may be dispensed with,

or the flat spring may be conveniently located in the chambered capresting upon the base and against the inner and upper surfaces of thecap.

It will thus be clearly seen that the present invention provides a veryeflicient and exceedingly simple bag fastener, the lsame beingconstructed of a minimum number of parts, and reduced to the simplestoperative efficiency.

We are aware that changes may be made in the several arrangements of thevarious parts, as well as in the details of the construction thereof,Without departing from i the scope of our present invention, hence we donot wish to be limited to the exact arrangements and combinations of theparts, as herein shownl and described, nor do We confine ourselves tothe exact details of the construction thereof.

We claim:

1. In a bag fastener, the combination of a chambered and slotted base, aslidable locking member secured to said base, and )rovided with weakenedintegral slotted lugs for permitting movement of the same, a centraldepending locking element secured to said locking member, and a springlocated in said slotted base in engagement with the said slotted lugsfor retaining the locking member in position and said spring providedwithan opening through which the locking element of said base passes.

2. In a bag fastener, the combination of a chambered base, a lockingmember slidably secured to said base and provided with depending lugs,said lugs provided with inwardly extending slots, the metal of the lugadjacent to said slots being turned inwardly to slidably secure thelocking member to the base, and for permitting movement of the same, acentral depending locking element secured to said locking member and aspring located in said base in engagement with the said depending lugsfor retaining the locking member in position.

This specification signed and witnessed this 11th day of January, 1910.
